Asp.net核心模型不受形式约束

Question

我从第三方静态页面(由Adobe Muse生成)捕获发布请求并使用MVC操作处理它.

<form method="post" enctype="multipart/form-data">
   <input type="text" name="Name">
   ...
</form>

路由空表单操作:

app.UseMvc(routes => routes.MapRoute(
   name: "default",
   template: "{controller=Home}/{action=Index}"));

但是根据行动我有模型,每个属性都是空的

行动:

[HttpPost]
public void Index(EmailModel email)
{
   Debug.WriteLine("Sending email");
}

模型:

public class EmailModel
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Company { get; set; }
    public string Phone { get; set; }
    public string Additional { get; set; }
}

Request.Form 从表单中获取所有值,但模型为空

[0] {[Name, Example]}
[1] {[Email, Example@example.com]}
[2] {[Company, Hello]}
[3] {[Phone, Hello]}
[4] {[Additional, Hello]}

Answer 1

注意不要为action参数指定与model属性相同的名称,否则binder将尝试绑定到参数并失败.

public async Task<IActionResult> Index( EmailModel email ){ ... }

public class EmailModel{ public string Email { get; set; } }

将actions参数'email'更改为其他名称,它将按预期绑定.

public async Task<IActionResult> Index( EmailModel uniqueName ){ ... }
